Answer 1

This is duplicate of Gradle 5 JUnit BOM and Spring Boot Incorrect Versions .

The solution is to add the following to your Maven POM.

<properties>
    <junit-jupiter.version>5.4.0</junit-jupiter.version>
</properties>

I have faced similar issue after updating spring boot dependencies to latest version and updating Juiper engine version to 5.6.1 has resolved my issue.

<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>5.6.1</version>
<scope>test</scope>
